我没有wifi网卡但是能wifi上网???

xifangczy · 2023-05-08 18:02:14

我这是主机PC 没有内置也没有外置无线网卡
主板华硕 Z97-A

确实能连我甚至还拔了网线只是速度非常非常的慢

之前都没有这个wi-fi选项今天开机很奇怪突然出现

网络管理用的 networkmanager 之前安装过 modemmanager usb_modeswitch

到asus官网找到你这款主板的规格参数，网络功能一栏有两个，估计是这个“802.3az节能以太网设备”

没了就不用贴了。等它哪天回来了再看。

很多主板都是自带无线网卡的,但是不自带天线
没有天线就会无线网非常慢

xifangczy · 2023-05-23 18:15:17

找到原因了... 我电脑上常年插着xbox无线手柄接收器... 是老款一代无线接收器... 取下后wifi立马消失

猜测应该是无线接收器使用2.4Ghz频率来连接手柄... networkmanager刚好可以利用接收器来连接wifi?? 很神奇...

恩，xbox手柄接收器会被linux当成无线网卡，除非安装了 xone 驱动： https://github.com/medusalix/xone
